[SOLVED] Monsters doing no damage (can only "Miss")

Sooo having literally just killed King Pepe, I decided to just stay and train there on the captain and helmet pepes without ever leaving the field. A whole five minutes had passed by the time I realized I wasn't taking any damage -- it's always a "Miss". Literally just stood in a mob to test it out. I'm like some kind of invisible ghostly murderer to these poor pepes.

Bug?? Stroke of luck??? Regardless, I'm assuming this problem will most likely fix itself if I leave the field sooo just going to spend some time auto-ing here for the foreseeable future.  

This happen to anyone else after a boss? / try it out!

Once you kill King Pepe, you become invulnerable to all monsters on that map. Once you relog or leave the map, they'll start doing damage to you again.

Not just you. I have noted it in a part of my ab mushroom guide. Just leave your phone on and auto combat

Ooh, I see I see. So yeah, in that case I'll just hang around here for a bit hehe Thanks, King Pepe!

Someone should post this to Tips n Tricks! I haven't gotten to King Pepe yet so I'm not confident enough in writing a blurb about it, lol
